Bio-based insulation by 123Isolatie

More and more homeowners choose insulation materials that not only perform well, but also offer a more sustainable option. Bio-based insulation is made from natural or renewable raw materials and can be an interesting alternative to traditional insulation materials.

At 123Isolatie we look at the home, the construction and your preferences. Based on that, we determine which bio-based insulation material fits the situation best.

Our approach is simple: careful workmanship, efficient insulation, and high-quality materials at a fair price.

Why choose bio-based insulation?

Bio-based insulation materials are made from natural or renewable raw materials. Examples include wood fibre, cellulose and other plant-based fibres.

In addition to reducing heat loss, these materials can contribute to a comfortable and pleasant indoor climate.

Bio-based insulation can contribute to:

  • Less heat loss
  • More comfort at home
  • Good sound insulation
  • A pleasant indoor climate
  • Better protection against heat in summer
  • A more sustainable way of insulating
  • The use of renewable raw materials

How does bio-based insulation work?

Like other insulation materials, bio-based insulation mainly slows down heat transfer.

The insulation layer largely traps air and therefore limits heat conduction and air movement.

Depending on the material, bio-based insulation can also regulate moisture and retain heat for longer. That can be especially interesting for certain roof, wall and timber-frame constructions.

Bio-based insulation and moisture

With natural insulation materials, a correct moisture-technical build-up is important.

A roof, wall or floor must be constructed so that any moisture can be drained or dried properly.

That is why we assess in advance:

  • The existing construction
  • The different building layers
  • Presence of membranes
  • Ventilation
  • Any existing insulation
  • The structure’s ability to dry out

Is bio-based insulation suitable for every home?

Not every bio-based insulation material is suitable for every construction.

The best choice depends on:

  • Type of home
  • Existing construction
  • Available space
  • Desired insulation value
  • Moisture-technical properties
  • Desired sound insulation
  • Desired finish
  • Available budget

Which bio-based insulation materials can we use?

At 123Isolatie we can apply several bio-based insulation materials. The choice depends on the construction and the desired insulation performance.

Gutex Thermofibre wood fibre

Gutex Thermofibre is a wood-fibre insulation made from wood fibres. It can be used in various constructions and offers good sound insulation and summer comfort as well as thermal performance.

  • Bio-based material
  • Good thermal properties
  • Good sound absorption
  • Good heat buffering
  • Interesting for summer comfort
  • Suitable for various roof and wall constructions

Easycell cellulose insulation

Easycell cellulose insulation is made from cellulose fibres and can be used to insulate cavities, among other applications. Cellulose fits well around existing structural elements, making it interesting for hard-to-reach or irregular spaces.

  • Bio-based and circular material
  • Good thermal insulation
  • Good sound absorption
  • Suitable for cavities
  • Fits well around structural elements
  • Interesting for various renovation applications

Which bio-based material fits best?

There is no single bio-based insulation material that is best for every home. That is why we assess each situation individually and advise based on construction, moisture control, space and budget.

  • Home type and construction
  • Available space
  • Desired insulation value
  • Moisture-technical build-up
  • Sound insulation
  • Finish and budget

Our bio-based insulation process

  1. 01

    Construction inspection

    We review how the existing construction is built and how much space is available.

  2. 02

    Assessment of the current situation

    We look at existing insulation, membranes, moisture, ventilation and possible points of attention.

  3. 03

    Advice on the right material

    Based on the home, we determine which bio-based material fits best — for example Gutex Thermofibre or Easycell cellulose.

  4. 04

    Careful installation

    The insulation material is installed accurately, with attention to good joints and as complete an insulation layer as possible.

  5. 05

    Focus on moisture and airtightness

    Where needed, we pay extra attention to vapour control, moisture regulation and airtight connections.

High quality at a fair price

At 123Isolatie we don’t only look at price — we focus on what technically and practically fits your home best.

Our approach is based on: the right analysis + the right bio-based material + a correct construction + careful installation.

Whether you choose Gutex Thermofibre, Easycell cellulose or another suitable bio-based insulation material, we look for a solution that fits your home and preferences.
